Chapter 259 Please

Chapter 260 Please

"Captain Huang... do you remember the last time we met?" Wan Baoming walked a little further away, holding a mobile phone in his hand, his head lower than his shoulders, his waist bent.

It's not easy to be a deputy director, there are not many things that can be shown, but Huang Qiangmin has a big appetite.

There is a trace of crystal in Wan Baoming's eyes.

It's not easy to do something.

Jiang Yuan couldn't see Comrade Wan Baoming's eyes and expression. He sat on the other side of his study, almost 20 meters away from the corner chosen by Wan Baoming, and even couldn't hear Wan Baoming's words clearly.

Of course, Jiang Yuan was not interested in listening to him and Huang Qiangmin quarreling.

He turned on the computer himself, put the fingerprints that Wan Baoming brought in, and processed them simply with Photoshop.

After doing fingerprints for a long time, Jiang Yuan was able to make some judgments before matching with the software. Whether it can be matched, how similar the matched fingerprints are, these can all be predicted.

Generally speaking, if a fingerprint with too much incompleteness is not processed by image software first, it is possible to match it with any monster.

Of course, it is also possible to match the correct fingerprint, but for technical personnel, playing this probability game is meaningless. Those LV2 level trace inspectors may only use this method to cover the task when doing extremely difficult fingerprints, but for Jiang Yuan, he has already surpassed this level.

He must be at least level 2 now, and the latter 2 must beat a lot of people.

The experience of doing a lot of difficult fingerprints and always succeeding is invaluable in itself. It's like an ordinary person who has been in the position of president for a long time and can gradually figure out some experience.

The fingerprint that Wan Baoming brought this time was a little too incomplete. According to Jiang Yuan's experience, now throwing it into the fingerprint software for matching, the answer obtained is equivalent to random.

This is not surprising. If the difficulty did not exceed the LV3 level, why would Wan Baoming be so humble.

A few minutes after Wan Baoming and Huang Qiangmin talked, Wan Baoming came over with his mobile phone and whispered, "Jiang Yuan, your team leader Huang's phone number."

"Okay." Jiang Yuan took the call.

"Jiang Yuan, how was your rest? Are you tired?" Huang Qiangmin asked with a smile on the phone.

"Not bad. I worked on the wall all day today and sweated a little." Jiang Yuan said.

"Sweating is good. Sweating makes the body feel good." Huang Qiangmin laughed and said, "Wan Baoming gave you another fingerprint? It's time to take advantage of the situation. Is the fingerprint he took this time difficult?"

"High. The probability of making it directly is not high." Jiang Yuan said.

"Oh, can it be compared? Can you give a comparison?"

"That depends on whether Curry has fingerprints." Jiang Yuan paused and said, "Even if Curry has fingerprints, it depends on the quality of Curry's fingerprints..."

"Give a number, how sure are you that you can make it?"

"Six." Jiang Yuan looked at Wan Baoming and didn't hide it too much.

Analyzing from the keywords alone, Jiang Yuan felt that Wan Baoming must have sought help from the fingerprint experts of the ministries.

But to be honest, the fingerprint experts of the ministries may not be at the level of LV4. There are powerful experts, and there must be more than LV4, and there may be LV5 masters.

But experts also need to talk about probability and investment.

Can Wan Baoming invite a strong enough fingerprint expert and ask the other party to devote himself wholeheartedly?

It is estimated to be difficult.

It is more likely that the other party will help to see, and if they cannot match in a short time, they will give up.

After all, the experts of the ministries are very busy. There are more than 30 provinces like Shannan Province in the country, and even experts may not be able to produce a super difficult fingerprint in a week.

This is like during the fingerprint battle, the normal experts at the level of Shannan Province and Department, the whole battle lasts 15 days, and they can look at about 100,000 fingerprints. It is good to match a few.

The intensity and importance of the battle are completely different from daily help.

Jiang Yuan only said to Huang Qiangmin: "This fingerprint is normally done in the province, and there is little hope."

Huang Qiangmin then understood and said happily: "Okay, then you give the phone to Wan Baoming, I will ask him to make up for the cost of the fingerprint."

Jiang Yuan smiled: "It took more than two hours to get the fingerprint."

"Others have told me that it depends on the computing power." Huang Qiangmin said confidently: "Give the phone to Wan Baoming, don't feel sorry for him, Changyang City is a rich place, a little leakage through the finger gap is enough for our small county to struggle for 10 years."

Jiang Yuan laughed and returned the phone to Wan Baoming.

Wan Baoming took it with great care, put it solemnly to his ear, and said: "Captain Huang, my little Wan..."

Wan Baoming continued to walk to the corner while talking.

Jiang Yuan sat back in front of the computer. Before the host computer started to roar, Jiang Yuan could vaguely hear some very mysterious keywords:

"Please."

"I'm really worried."

"Captain Huang~"

"Please give me a hand..."

...

After a long time, Wan Baoming handed the phone with a hot back cover to Jiang Yuan.

Jiang Yuan: "Hello. Captain Huang."

Huang Qiangmin: "Let's take a look at it. I'll ask them to send two people over to give us training. In addition, let's borrow some of their old equipment and so on. I still have the opening. You can see it later. Whatever you want, tell me what you want."

Jiang Yuan said a little embarrassedly: "Okay."

"Okay, turn on the speakerphone." Huang Qiangmin said.

Jiang Yuan then took off his cell phone and turned on the speakerphone.

Huang Qiangmin's voice came out: "Jiang Yuan, you have to do a good job with Director Wan's tasks. You still have two days of vacation, so don't take it now. Go to work again. Once you finish it, you are here Hugh. Changyang Criminal Division Center has helped us with many cases before. You should cherish the opportunity to cooperate this time..."

"Yes." Jiang Yuan responded politely.

"Director Wan, I'll leave Jiang Yuan to you. Young people are immature and if they don't do well, please bear with me. If you have any questions, just come to me directly and I'll criticize him..." Huang Qiangmin chattered. He ended the call nagging.

Wan Baoming put away his cell phone and sighed: "You, the yellow team, are not as easy to talk to as before."

Jiang Yuan just smiled and said nothing.

Borrowing someone else's big green cow to plow the land is probably not the same as borrowing a cat to catch mice.

When the mouse moved, the computer whined.

In terms of image rendering, no matter how high the configuration of the computer, the sound is the same. This is just like that, right?

"Director Wan, can you please introduce the case?" Jiang Yuan took this time to ask Wan Baoming.

"This is a case at the Maixin Electronics Factory last year. A female worker was pushed down on the roof of the building. At first, she thought she was committing suicide. Later, an eyewitness said that she saw two people on the roof of the building, and there were The pushing action..." Wan Baoming described the scene, and then focused on the evidence:

"The early dispatch of the police was actually a bit problematic, because at first it was thought to be suicide, so the on-site protection was not very good. The factory security guards and workers all ran to the roof of the building."

"Secondly, there are only eyewitnesses and there is a lack of surveillance video. Because everyone is wearing work clothes, it is not easy to judge the murderer."

"The third thing is that the workers in the factory are not very familiar with each other. This Maixin factory adopts a hiring and recruiting model. It means signing a large OEM order and recruiting a group of workers to come and work. If it’s almost done, we’ll fire it and wait until there’s a big deal next time. So, it’s not easy to solve the case based on social connections.”

Jiang Yuan listened to Wan Baoming's introduction and couldn't help but ask: "Then the only evidence is the fingerprints on the clothes?"

Wan Baoming sighed: "The problem now is that the fingerprints on the clothes have become reverse evidence. Several suspects that the criminal police focused on questioning have been eliminated by the fingerprint evidence on the clothes..."

Jiang Yuan couldn't help but smile when he heard this, and then asked: "Then everyone in the factory should have their fingerprints taken?"

"I picked it up. When something happened, the factory was immediately closed, and all the entrances and exits were under video surveillance."

Jiang Yuan couldn't help but nodded. In this way, the problem of the fingerprint database was actually solved.

From the perspective of a fingerprint examiner, this is a perfect environment for fingerprint comparison. You only need to make fingerprints and you can do the comparison.

Thinking of this, Jiang Yuan frowned again and said: "The core problem is to match fingerprints. We really couldn't match last year's case. Matching one person at a time can always be done..."

Wan Baoming couldn't help but smile, and quickly covered it up, saying: "I just said that the factory belongs to Maixin. You may not know much about it. At that time, the factory received a large order and was at full workload. There are 10 workers in the factory area. Nearly 30,000 people.”

Jiang Yuan suddenly realized.

For a large factory with tens of thousands of people, it is definitely unrealistic to compare fingerprints one by one, especially when the fingerprints are in such poor condition.

"What did you use to extract fingerprints? 502?" Jiang Yuan looked at the fingerprints and gradually entered the state of fingerprint comparison.

Wan Baoming understood Jiang Yuan's hidden meaning and smiled bitterly: "Yes, 502 Xunxian."

Similar to ninhydrin fumigation, the 502 glue fumigation method is also a method of revealing latent sweat fingerprints after applying chemical reagents.

Similarly, all similar solutions actually have a layer of problems that people rarely talk about, and they are prone to defects in operation.

Criminals leave fingerprints accidentally, but if the fingerprints are damaged and incompletely displayed, they will definitely not give another copy.

Just like the fingerprint in front of me, it was so damaged that the fingerprint inspection had to be difficult to match. Usually I have to complain about fingerprint extraction. Usually the ones who get scolded are also current surveyors.

Jiang Yuan used image software to slightly adjust the fingerprints, and gradually came up with an idea.

Feeling energetic, he was too lazy to pay attention to Wan Baoming and said, "If you don't play like a dog, I will tell you the results."

"Okay." Wan Baoming responded before he finally came to his senses: "Should I wait here?"

"Then... if you have something to do, go ahead and do it." Jiang Yuan naturally didn't care.

Wan Baoming said hurriedly: "That's not what I meant, I meant... uh, will the results be available today?"

"It's possible. The main thing now is to process the image. This fingerprint is taken from cotton clothes. Cotton, a natural fiber, is spirally twisted. The cross section of the fiber is like a waist, and it is easy to get lint. This is caused by sweat. The main reason why fingerprints are not expressive enough..." Jiang Yuan explained to Wanbao Minglue.

Wan Baoming looked at Jiang Yuan and said: "I have also done a trace inspection, and I understand the truth, but..."

Jiang Yuan was silent for a moment, and then said: "If you are bored, why don't you go back to Changyang City and send the people and things that Team Huang wants to him? Send them to him and come back. I almost have them here. Result."

He has now processed nearly half of the images, and the clarity of the images he consciously processed is acceptable. Considering that Changyang City has collected the fingerprints of everyone in the factory, it means that the comparison library is complete, and the possibility of matching is very low. Greatly increased.

In fact, if the fingerprint cannot be compared in this case, the matter itself will be very meaningful and valuable.

Therefore, the answer given by Jiang Yuan is very certain.

Wan Baoming felt that Jiang Yuan was a bit crazy, but looking at Jiang Yuan's expression, he didn't notice the madness.

"Okay. I'll go back first and report to the leader. I'll come back and wait for your good news." Wan Baoming restrained all his emotions.

His philosophy is that as long as you can make something, I will obey you.

With this thinking model, Wan Baoming's own abilities were average, but he was recognized by many criminal investigation experts, and then became the deputy director of the Changyang Criminal Investigation Center.

Within the Criminal Division Center, Wan Baoming is also a relatively recognized leader. It is also because he is a kind of person who respects technology more.

As long as Jiang Yuan can make things, Wan Baoming can accept the combination of Jiang Yuan and Huang Qiangmin.

But if it doesn't work, then Wan Baoming will have to talk to Huang Qiangmin and Jiang Yuan.

After leaving the house and getting in the car, Wan Baoming even started talking to the group in advance:

Daily depression: [He took the backlog of murder cases from last year and found Jiang Yuan. It’s a super difficult fingerprint. I didn’t expect Jiang Yuan to answer it immediately. Now I’m going to move bricks and change fingerprints...]

South Expedition Bei Zhan: [I’ve only heard of moving bricks for 30 days and going to the club on the 31st. What the hell is moving bricks for fingerprints? 】

Daily depression: [Team Huang made some conditions, I have to prepare some resources for him. You can't let people work for nothing. No, what the hell are you doing carrying bricks to the club? "

Southern Expedition and Northern War: [Moving bricks is so tiring, if it wasn’t for going to the club, it would be a tearjerker. 】

Daily depression: [What if there is no number 31? 】

Southern Expedition and Northern War: [You are moving bricks, not robbing banks. It will take you two months to save enough money? 】

Daily depression: [It makes sense...]

Fighting in the South and North: [What conditions did the Yellow Team set? Do you still have to prepare resources? 】

Daily depression: [A few technicians, a few pieces of equipment, and the technicians brought an on-site survey vehicle over. 】

Fighting in the south and in the north: [So good? Got a new car again?

I was scrolling through my cell phone in the car and couldn't help but sit up, frowning and typing:

Daily sluggishness: [No, who are you x-on:南尊北War]

Fighting in the north and south: [I... am just a man who has traveled extensively, accumulated some experience and is willing to share it. 】

Ningtai County Criminal Police Brigade.

Sitting in the office, Liu Wenkai, who was bored, let out a long breath, raised his head again, and said to the squadron instructor: "Let's also find two backlogged cases and start a tough battle."

"Looking for the blame? Are you done with the case in hand?" the instructor sneered.

Liu Wenkai chuckled and said in a low voice: "I received rumors that our team will probably have a few new temporary workers, some of whom are technical."

"So good?" The instructor was very surprised: "We have no organization for a long time, where did we get the people we deceived?"

"The criminal police team from Changyang City came here for support. Probably."

"Reverse secondment?"

"I guess. Do you want it?" Liu Wenkai said calmly: "If you want people, don't you have to have a project?"

"Okay, okay, open the backlog, open the backlog." The instructor said twice. For a squadron that is busy every day, there is nothing more comfortable than adding more manpower.
